I have a Takahashi FSQ106 scope and would like to add a Tak Reducer QE 0.73X to the train. The reducer has 77mm male threads on the OTA side and 55mm male threads on the camera side.  My problem is how to mate the reducer to an adapter that on the camera side receives my 2" nosepiece (connected to filter wheel and featuring thumb screws). Currently my adapter screws directly into the OTA.  I bought a complete set of step up and step down rings hoping one of them would solve the problem but the threads are wrong (male/female wise). 

 

Plenty of folks use the reducer so I know there's a solution.  Adapters that receive a 2" nosepiece with thumbscrews don't seem to come with much variety of thread sizes on the other end.  Thanks for any ideas.

I suggest that you email or call Texas Nautical Repair.

Looks like they're permanently closed.  Thanks for the tip, though.

I stopped by there just the other day last week. Saw no indication of them closing up.

Their website won't come up on my PC. My phone (different network) says "permanently closed".

 

OP try contacting Takahashi America (talk to Christopher H.) and ask for the system chart for that reducer. 

 

Here is a chart But that chart only shows a threaded connection to a camera.

geoffoto,

I am sure you have this PDF??

 

Question, why use a 2" nosepiece when you could have a threaded connection, unless I misunderstood you? You might need to go to Precise Parts (assuming you are in the US, not sure if Ashley ships international) and have an adapter made to go from the QE to your filterwheel since the spacing from the QE reducer to the camera sensor needs to be precise at 72.2 mm from the 0.73 reducer shoulder. You also need to compensate for filter thickness and possibly your camera's sensor coverslip.  

 

This topic has been exhaustively discussed here on CN more than once. Here is a good thread to check.

 

Good luck!
